i Filed Feb. 3, 1960, Ser. No. 6,486 "4 Claims. (Cl. 248-311) This invention relates to what are generally referred to as aerosol cans or containers, wherein a vapor or the like is discharged through a manually operated nozzle at one end of the container. More particularly, the invention deals with a bracket-type of mounting adapted to be secured toj'ai suitablejsupport, the bracket having coil spring meansadapted .to detachably engage an undercut recessed portion in the upper discharge end of the can or container in support thereofin connection'with the bracket mounting. Y a Y 3 Still more particularly, the-invention deals with a bracket mounting, the cpil'spring supporting portion of which includes means retaining the springagainst circumferential movementthereon'in the operation of coupling 'and'uncoupling a can or container therewith.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

FIG. 1 is a face view of a bracket mounting made according to my invention and illustrating in dotted lines the general position of an aerosol can arranged therein and diagrammatically illustrating the mounting spring.

FIG. 2 is a section substantially on the line 2-2 of FIG. 1, omitting the can or container and again diagrammatically illustrating the mounting spring.

FIG. 3 is a plan view of the structure shown in FIG. 1.

FIG. 4 is an enlarged sectional view through the coil spring mounting portion of the bracket, the section being on the line 4--4 of FIG. 5, but omitting the can or container of FIG. 5.

FIG. 5 is an enlarged view of the upper portion of an aerosol can or container, parts of the construction being broken away and in section and indicating that part of the mounting bracket supporting the coil spring and illustrating operative engagement of the spring with the undercut recessed portion of the container; and

FIG. 6 is a sectional portion of the structure, as seen in FIG. 4, but illustrating part of the can or container of FIG. 5 on the line 66 of FIG. 5 to illustrate fiexure of the coil spring in passing over that part of the container on the line 66.

In carrying my invention into effect, I provide a bracket mounting 10 which can be composed of any suitable material, but is preferably formed from molded plastics, the bracket being defined by a top wall 11, a back wall 12 and side walls 13. The top wall 11 includes, at its forward edge, a projecting portion 14 note FIG. 3 of the drawing, and this portion, including the top wall, includes a downwardly extending integral sleeve 15, which forms part of a support for a coil spring 16, the sleeve having a recess 17 in its lower peripheral edge, in which the spring 16 seats, this recessed portion being sub-divided, however, by a plurality of key ribs 18, four of which are shown clearly in FIG. 4 of the drawing. The key ribs 18 are adapted to fit between coils of the spring 16 to prevent circumferential movement of the spring in the recess 17. For further support of the spring on the sleeve 15, a metal bushing 19 is mounted in the bore 20 of the sleeve, note FIG. 5 of the drawing. The lower or inner end portion of the bushing 19 is fashioned to :form a circumferential spring retaining rim 21, which overlies the recess 17, as clearly indicated in FIG. 5, thus definitely retainr 2 ingthe. spring against displacement from the sleeve 15. The strands from which the springs 16 are formed are secured at adjacent ends, as diagrammatically illustrated at 22 in FIG. 4 of thedrawing.

At 23'I have indicated in FIG. 5 of the drawing the upper portion of an aerosol can orcontainer, the same being also indicated in dotted lines in FIG. 1 of the drawing. Containers of this type and kind are usually fashioned to form in the upper recessed portion 24 thereof an inwardlyextending head 25', which is of less diameter than the diameter of the recess 24 and this bead willserve to securely support :the'can "or container 23 in connection with the bracket. 7 The can or container 23 has the usually manually operated discharge 26 and itwill be apparent, from a consideration of FIG. 5 of the drawing, thatithe bore with the bushing '19 therein is sufficiently large to freely receive 26 as it passes upwardly'therethrough in the operation of coupling the can or container 23 with the bracket. In operation, the inwardly extending bead i25'wil1 flex the coils of the spring in the manner diagram- "maticallyilllustrated inFIG. 6 of the drawing in passage over the spring and, in this operation, it is desired that the can or container 23 be rotated slightly to aid in flexing of the coils and, upon entering the recess 24, the coils of the spring will flex outwardly to their normal position, as noted in FIG. 4 of the drawing, and securely retain the can or container 23 against displacement from the bracket. In the operation of removing the can or container from the bracket, the above operation is reversed, in other words, a downward pull and slight rotation is applied to the can or container and, here again, the coils of the spring will be flexed to freely release the can or container.

Considering FIGS. 1 and 2 of the drawing, it will appear that, in the production of the bracket, the back wall will be provided with a number of apertures 27 for mounting the back wall 12 upon a suitable support and, further, the side walls 13 are provided with spaced notches 28, as clearly noted in FIG. 2 of the drawing, for support of the bracket on either of the side walls. It will also appear that the bracket is reinforced by a central rib portion 29 to clearly resist stress or strain to which the top wall 11 of the bracket may be subjwted in attachment and detachment of the can or container therewith.

It will be understood that, while the foregoing describes one adaptation and use of my bracket mount, it will be apparent that the same may be utilized in support of any type or kind of device having an undercut recessed portion which can be attached and detached with respect to the coil spring mounting element of the bracket.

It will be apparent that the diameter of the spring is greater than the diameter of the sleeve, so that at least half of the spring coils are extended beyond the sleeve diameter to form a circumferential gripper portion on the spring for engaging an article in the support of an article in connection with the bracket. It is this gripper portion which is flexed by the article in attachment and detachment of the same with said spring.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A bracket of the character described, defined by top, back and side walls, the top wall having a depending sleeve, the lower end of the sleeve having a peripheral recess, a coil spring arranged in said recess, means on the sleeve retaining said spring against displacement from said sleeve, the coils of the spring being of greater diameter than the diameter of said sleeve to form, at the periphery of the spring, circumferential gripper portions for engagement with an article coupled with the bracket, and the coils of the spring being adapted to be flexed in engagement of an article with said spring.
